Get firewall zone

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and openWorld, so safety is covered. The description adds nothing beyond that – no note on what constitutes a valid zone identifier, whether an error is returned for unknown IDs, or what the payload contains.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

It is a single front-loaded clause with no waste, which is good, but the brevity comes from under-specification rather than efficiency. There is nothing to trim and equally nothing of substance retained.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and no parameter documentation, the description is the only source of semantics for a by-ID lookup tool, and it supplies none. An agent knows only that it returns something about a firewall zone, not what fields or behavior to expect.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the sole required parameter "id" is completely undocumented. The description does not say whether this is a zone UUID, a numeric ID, or a name, so it fails to compensate for the schema gap as the low-coverage rule requires.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

"Detail for one firewall zone" essentially restates the tool name and title rather than stating a verb+resource operation. It minimally distinguishes a single-zone fetch from the sibling list_firewall_zones, but only by implication of the word "one".

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance, no prerequisites, and no explicit mention of the sibling list_firewall_zones vs this single-zone variant. The agent must infer that this is the by-ID counterpart to the list tool from naming conventions alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
